"Mike, if you run the pulse thru the reeds you'll only get the vacuum half of a normal pulse wave. The pump diaphragm of the tillo would normally rely on the pressure half of the wave to push/flex the diaphragm back in the other direction.…"
Entries are flowing in for the Robert Harrison Memorial Trophy for Twin Supers to be run at the Australian Vintage Kart Prix. The memorial trophy was originally run for 200cc Supers in the early 90's and will be restored for the event, and I plan to make it an annual Vintage Twin event that can be run in conjunction with Vintage events from year to year.
We are also promoting the class to the Yanks and they are very interested, so yes C Open is invited for the Ipswich event.
We already have 9 Twin Super entries, some made up of 130-135cc karts.
I expect we could see more than 20 Vintage Twins at the event.
I think we will need to also put up a trophy for 130-135cc.
Hi Mark - trust you are well? Heard out of nowhere from Kevin Iapozzuto & Wayne Calder recently, both have extraordinary tales of the past 10 years - what news from you? Dean Lindstrom and myself racing my RX3 at Winton this w/e in a 300km endurance race - crazy short notice I know, but Sue and yourself up for a road trip? We've got a house at Jamieson with heaps of accom. Either way lets catch up. Cheers Brett
